Abstract: ABSTRACT OF DISCLOSURE   Disclosed herein is an apparatus which is adapted for controlling operation of an internal combustion engine which is selectively operable using gaseous fuel or liquid fuel, and which comprises a gaseoud fuel supply line extending between the engine and a source of gaseous fuel, a liquid fuel supply line extending between the engine and a source of liquid fuel, and a control for controlling supply to the engine of the gaseous fuel and the liquid fuel, which control includes an operator controlled fuel selector switch movable between a gaseous fuel position and a liquid fuel position, which control is operable following prior engine operation with gaseous fuel and in response to movement of the fuel selector switch from the gaseous fuel position to the liquid fuel position for permitting liquid fuel flow through the liquid fuel supply line, for permitting continued gaseous fuel flow through the gaseous fuel supply line until initiation of liquid fuel combustion, and thereafter preventing further gaseous fuel flow through the gaseous fuel supply line until repositioning of the fuel selector switch to the gaseous fuel position, and which control is also operable following prior engine operation with   liquid fuel and in response to movement of the fuel selector switch from the liquid fuel position to the gaseous fuel position for preventing further liquid fuel flow through the liquid fuel supply line, for preventing gaseous fuel flow through the gaseous fuel supply line until termination of  liquid fuel com-bustion, and for thereafter permitting gaseous fuel flow through the gaseous fuel supply line until repositioning of the fuel selector switch to the liquid fuel position.

Abstract: PRINT RIBBON PROTECTION           Background of the Invention Field of the Invention This invention relates to ribbons for printers and relates more particularly to a system to give such ribbons improved life and print quality.            Description of the Prior Art In some printing systems, it is desirable to employ an endless ribbon and a stuffer box to provide a low cost  ribbon system.  The stuffer box is used to store the excess ribbon in the ribbon loop, this excess being fed or "stuffed" into the box.  There are three major problems which may arise from the use of such an endless ribbon.  First, when the nylon ribbon is spliced, the narrow splice area of the ribbon does not readily accept ink so that this area is unsuitable for printing. Secondly,  the ribbon splice area is less able to withstand print forces than the rest of the ribbon, thereby resulting in a high likelihood of ribbon failure at the splice area if printing is attempted on this area. Thirdly, if the ribbon jams in the stuffing box area, or elsewhere in the ribbon path, the ribbon ceases to be fed past the print mechanism and will be destroyed by the action of the print mechanism.  Therefore,  it  is desirable  in  such  printing  systems  to  provide indications of the approach of the ribbon splice to the print station and of lack of ribbon motion indicating a ribbon jam.              Prior Art U.S. Patent No. 3,949,856, issued April, 1976, to Ulber et al shows the use of a roller mechanism to detect medium movement to indicate medium jams.

Abstract: La présente invention a pour objet une méthode perfectionnée de régulation automatique du moment de commande de l'initiation de la combustion d'un moteur à combustion interne. Le moteur comporte au moins un cylindre muni d'un détecteur des positions angulaires de l'arbre moteur correspondant à l'apparition d'au moins un phénomène caractéristique des conditions de fonctionnement du moteur lorsque ce phénomène et/ou sa détection présente un caractère aléatoire. La méthode est caractérisée en ce que pour ledit cylindre, on mesure la position angulaire de l'arbre moteur au moment où apparaît le phénomène, puis lorsqu'au moins un certain nombre de mesures validées a été obtenu pendant un nombre de cycles au plus égal à une première valeur prédéterminée, on détermine une valeur angulaire statistique représentative des mesures validées et, à partir de cette valeur statistique, on détermine et on applique aux moyens de commande une valeur modifiée du moment de commande de l'initiation de la combustion de manière à ce que la valeur statistique prenne une seconde valeur prédéterminée.

Abstract: ABSTRACT OF THE DISCLOSURE:         A tree processing unit for use in combination with a motorized carrier.  The unit comprises a base support pivotably mounted on and extending up from the carrier, which comprises a pair of spaced apart side plates parallel to each other and defining a through passage between them. An elongated, tubular base is fastened to the upper ends of the side plates of the base support.  This base extends above the through passage defined by the side plates.  A rigid, elongated boom is movably mounted through the base and has a front end on which is fixed a tree processing head for gripping and debranching a felled free.  Means are fixed onto the base in front of the support and the through passage therefrom for holding the processed tree.  In opera-tion, the felled tree which is usually picked up by the head, then pulled by the boom to the holding means, and subsequent-ly processed by the head moved forwards by the boom while the tree is held by the holding means, may be repositioned with respect to the holding means by using the head to push the tree back through the passage in the support.  This makes it possible to process trees even if their length is longer than the boom.

Abstract: Abstract A serial chain of N sorting modules is arranged to sort batches of up to N items in a desired sequence in accordance with the value of the items.  Each sorting module is arranged to compare two input items, to select one item for transfer to the next module, depending upon the relative value of the items, and to simultaneously accept the next item from the previous module.  The value of the items can be numeric, alphabetic, et cetera.  In accordance with the invention, each module is also arranged to detect the occurrence of an item having a unique value which indicates the beginning of a batch of items.  Upon detection, each module passes the items in the same order as they were received, independent of their value.         A chain of modules may be used to sort records each having data and an associated key by applying the keys to sorting circuits and the data to slave circuits.         Record sorting can be used to interchange the time slots of a time-division multiplexed signal, or to rearrange empty slots such that they can be utilized.

Abstract: ABSTRACT OF THE DISCLOSURE A shared encoder/decoder circuit for use with a Reed-Solomon coding scheme of an optical disk storage system.  The optical disk system (20) includes a drive adapted to permanently store data on a removable  platter  (44).   Prior  to recording a  data byte on  the platter,  the data is encoded with a Reed-Solomon code.  When the data  is read  from the disk,  it  is decoded and  error  correction syndromes are generated.  The same circuitry  (161)  is shared for performing  the  encoding  and  decoding  functions.   This  circuitry includes independent sets of a RAM (165), coupled to one input of an exclusive OR (modulo two sum) adding circuit (172).  The output of the adding circuit is fed back to an input to the RAM (165).  Two multiplier circuits  (168,  170)  are coupled  to the output of  the RAM.   A product of one is tied to one input of the modulo  two addition circuit  (172).  The product of the other is combined in another module two addition circuit (173) with similar products from other  sets,  and  the resulting combination  signal  is  selectively connected  to the other  input of  the modulo two addition circuit (172), along with data to be recorded on the platter, or data read from the platter.
